What Is the Gartley Pattern?

The Gartley pattern is a harmonic pattern used to assess a possible trend reversal when five chart points (XABCD) satisfy specific Fibonacci ratios. Here are the ratio rules, entry principles, and clear limitations.

What Is a Gartley Pattern?

The Gartley pattern is a chart formation introduced by H. M. Gartley in 1935. It is an M- or W-shaped harmonic pattern connecting five price points: X, A, B, C, and D. The central idea is to assess a potential reversal at D when each leg's retracement and extension align with Fibonacci ratios.

Its distinction is that it is a structure defined by ratios, rather than merely a shape seen by eye. A similar-looking pattern is not a Gartley if its ratios do not fit.

XABCD Structure and Fibonacci Ratios

Using the initial trend wave XA as the reference, later waves must follow specified ratios. Representative criteria are below.

The most important feature is D lying near the 0.786 retracement of XA. D becomes the potential reversal zone (PRZ).

How Are Entries and Stops Considered?

Traders using Gartley patterns usually look for a reversal at D (the PRZ). They consider buying near D in a bullish Gartley and selling near D in a bearish Gartley.

• Entry: After price reaches D and additional confirmation appears, such as a reversal candle or a change in volume.
• Stop-loss: Treat a clear move beyond D as pattern failure and place a stop beyond X.
• Target: Use previous structural points such as C or A as initial targets, managing exits in stages.

Limitations and Precautions

The Gartley pattern does not guarantee future prices. Patterns frequently fail even when ratios fit, and different people may select different X, A, B, C, and D points on the same chart. Although its rules appear objective, practical identification involves subjectivity.

• Broad ratio tolerances, such as a range around 0.786, can encourage hindsight interpretation.
• In strongly trending markets, the reversal assumption often fails.
• It is safer to combine the pattern with support and resistance, volume, and other evidence than trade it alone.

Summary

The Gartley is a harmonic reversal pattern defined by Fibonacci ratios, used to assess reversal potential at D, around a 0.786 retracement of XA. It is only a probabilistic scenario, not a formula guaranteeing success, and must be accompanied by stops and capital management.
